* This function returns strictly the differences between the tree and the
* files contained in the working directory, regardless of the state of
* files in the index. It may come as a surprise, but there is no direct
* equivalent in core git.
*
* To emulate `git diff <tree>`, use `git_diff_tree_to_workdir_with_index`
* (or `git_diff_tree_to_index` and `git_diff_index_to_workdir`, then call
* `git_diff_merge` on the results). That will yield a `git_diff` that
* matches the git output.
*
* If this seems confusing, take the case of a file with a staged deletion
* where the file has then been put back into the working dir and modified.
* The tree-to-workdir diff for that file is 'modified', but core git would
* show status 'deleted' since there is a pending deletion in the index.

* consider the example of a staged file deletion where the file has then
